My limited experience so far says no..... but I have a well insulated, well sealed, properly vented "attic" space.
I have an insulated chimney pipe going through the space in my scissors trusses, surrounded by a cathedral ceiling box and the special Selkirk insulation between the box and the pipe. So far, all I've seen is the snow eventually melts immediately around the chimney penetration, but it's slow, and stops there.....not enough to cause any damming so far.

Its not an issue on a house with adequate soffit, proper vents, ridge/gable end vents and ice and water shield under the roofing from the edge of the roof a minimum of 2' above the roof overhang. There is some radiant/conductive heat transmission from the pipe that can melt the snow around the pipe but rarely is an issue.
Well, the larger the temperature difference between 2 objects, the more heat will transfer. So heat is going to leave the pipe all along its length. The shorter the distance, straight up, the less chance the heat has to escape into the attic through the pipe.
So vent it straight up.
So vent it straight up.
